Iron deficiency among French whole-blood donors: first assessment and identification of predictive factors. Vox Sang 2020; 116:42-52. [PMID: 32965040 DOI: 10.1111/vox.12991] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2020] [Revised: 07/17/2020] [Accepted: 08/09/2020] [Indexed: 01/12/2023]
Abstract
BACKGROUND The objectives of this study are to estimate the prevalence of iron deficiency (ID) among French whole-blood (WB) donors to identify factors associated with ID and to generate decision trees. STUDY DESIGN AND METHODS A prospective National multicentre study was performed on WB donors from March 11, to April 5th, 2019. Samples were selected randomly to perform serum ferritin. ID was defined as ferritin value under 26 ng/ml. All results were stratified by sex. Factors associated with ID were analysed using multivariate logistic regression model. CART algorithm was used for decision trees. RESULTS Eleven thousand two hundred fifty eight WB donors were included. ID was more frequent in women (39·5%) than in men (18·0%). Among 7200 repeated donors, women below 50 yo had a higher risk (OR = 2·37; [1·97-2·85] IC95) than those above 50 yo. Factors associated with ID were: haemoglobin level under the threshold at donation n-1 except for women and n-2 donation; a low mean corpuscular haemoglobin at n-1 and n-2 donations; a shorter interval since n-1 donation and between n-1 and n-2 donations except for women; and women who had given three or four times in the last year. CART algorithm defined high risk of ID subgroups within three populations of donors, new female donors, repeated male donors and repeated female donors. In these identified subgroups, prevalence of ID was up to 72·1%. CONCLUSIONS Our study showed the high prevalence of ID among French WB donors, identified well-known and new factors associated with ID and defined algorithms predicting ID in three populations.

Abstract
BACKGROUND AND OBJECTIVES Each donation of a single whole blood unit causes a 200-250mg iron loss. The main clinical manifestation of iron deficiency among blood donors is anemia, and every blood collection establishment must have measures in place to minimize and prevent iron depletion in blood donors, according to the European guidelines. However, iron deficiency without anemia is also associated with clinical manifestations. The management of iron deficiency is an acute issue; still, no consensus on its managements exists. One possibility is iron supplementation; however, the acceptability of such a measure is still unknown, so we asked donors' opinions on this topic. MATERIALS AND METHODS Over a 2-month period, a questionnaire was voluntarily completed by blood donors at the French Military Blood Institute. Gender, age, number of donations in the last 12 months, and preference between iron supplementation and general practitioner consultation for management of iron deficiency were recorded. RESULTS One thousand nine hundred and seventy-four questionnaires were returned. Donors between ages 18-50 represented 89% of respondents. Altogether, 49% declared that they would rather visit their general practitioner and 46% would rather receive iron supplementation. There were no significant differences correlated with gender or age. However, a higher number of prior donations was significantly associated with a preference for iron supplementation. Frequent female donors had an even stronger preference for iron supplementation. CONCLUSION Our results showed that there are no strong objections to iron supplementation, which could be an acceptable option for frequent donors - the main population at risk for iron deficiency.

Abstract
OBJECTIVE This study aimed to evaluate the effect of oral iron supplementation in frequent donors in Korea, based solely on donation history. STUDY DESIGN The hemoglobin (Hb) level, ferritin level, soluble transferrin receptor (sTfR), total iron binding capacity (TIBC), and transferrin saturation of frequent donors at high risk for iron deficiency were compared to those of first donors. The frequent donors took iron supplements for 4 weeks and the same tests were repeated after 2 and 4 weeks to evaluate their effects. RESULT A total of 53 male and 57 female frequent donors were recruited. After 4-week iron supplementation, among the men, the prevalence of a: low Hb level (<13.0 g/dL) decreased from 25% to 2%; low ferritin level (<15.0 ng/mL) decreased from 58% to 4%; iron deficient erythropoiesis (IDE) (log(sTfR/ferritin) ≥ 2.07) decreased from 77% to 33%. Among the women, the percentage of a: low Hb level (<12.0 g/dL) decreased from 44% to 9%; low ferritin level decreased from 79% to 11%; IDE decreased from 95% to 47%. In total, 15 male (28.3%) and 29 female (56.9%) blood donors reported undesirable side effects related to iron supplementation. No serious adverse events were reported. CONCLUSION Ferritin level, a reliable indicator of iron status, increased and IDE decreased significantly after four-week iron supplementation in the female, but not in the male, donor group, compared to those of control donors. Four-week oral iron supplement was not enough to restore iron storage level in the male donor group.

Abstract
BACKGROUND AND OBJECTIVES We performed a prospective analysis of iron status in plateletpheresis donors, using whole blood donors as a control group, to assess the haematinic effects of regular anti-coagulated extracorporeal circulation and platelet collection. MATERIALS AND METHODS Ferritin levels were measured in samples from 31 regular male plateletpheresis donors and from 14 first time male whole blood donors, immediately before and immediately after donation, and immediately before the next donation. An additional 33 regular male plateletpheresis donors and 17 first time male whole blood donors had serum ferritin levels checked predonation. RESULTS Male plateletpheresis donors had a statistically significant fall in serum ferritin after donation (P = 0.005)*. In addition, male platelet donors had significantly lower serum ferritin levels than first time male blood donors: ferritin <20 µg/L was found in 6/64 (9%) of regular platelet donors and 1/31 (3%) of first time blood donors (P < 0.001)*. DISCUSSION Our studies support the value of serum ferritin measurement in apheresis donor management.
